Equipment

Ingredients

  • 2 cups All purpose flour
  • 1 teaspoon Baking Powder
  • 1 teaspoon Baking Soda
  • ½ teaspoon Salt
  • ½ cup Butter Melted
  • ½ cup Brown Sugar
  • ½ cup Granulated Sugar Plus for more rolling the cookie dough in
  • 1 teaspoon Vanilla Extract
  • 2 Eggs
  • 1 cup Peanut Butter
  • 1 cup Sourdough Starter Inactive not recently fed

Instructions

  • Preheat the oven to 375 degrees. In a small bowl, mix together the flour, baking soda, salt, and baking powder. Set that aside.
  • In the bowl of a stand mixer, add the melted butter, brown sugar, and white sugar. With the stand mixer fitted with the paddle attachment, cream the butter and sugar until well mixed and light in color.
  • Add the eggs and vanilla extract to the bowl. Mix again.
  • Add the sourdough discard and peanut butter to the bowl. Mix again.
  • Carefully add the flour mixture to the stand mixer and mix until combined. Cover the bowl with plastic wrap.
  • Let the dough rest in the refrigerator for at least one hour.
  • Add 1 cup of sugar to a bowl. With an ice cream scoop, scoop out the dough into the bowl of sugar. Roll the dough in the sugar and place the dough on a parchment lined baking sheet.
  • Press a fork into the cookie dough to flatten the dough. Cross hatch the dough with another fork imprint.
  • Bake the cookies for 12 minutes and then take them off the baking sheet and cool on a wire rack.

Notes

  • Add chocolate chips! Chocolate makes everything better! Add 1 ½ cups of semi-sweet chocolate chips to the batter.
  • Use crunchy peanut butter! To add some more texture to the cookies, use crunchy peanut butter.
  • Chop up peanuts! Just like crunchy peanut butter, salted peanuts will add a bit of salt and some crunch to the cookies.
  • Add peanut butter chips! To increase the peanut butter flavor, use your favorite variety of peanut butter chips.
